Divide dough equally into 12 pieces; roll each piece with hands on a lightly floured countertop to form 15-inch ropes. Form each rope into pretzel or other desired shape and place three inches apart on two nonstick cookie sheets. Brush pretzels with beaten egg. Sprinkle remaining 1/4 cup Asiago cheese and optional toppings, if desired, over pretzels.

Bake until golden brown, about 16-18 minutes. Immediately transfer pretzels to a wire cooling rack. Serve warm or at room temperature with mustard, if desired. Pretzels may be stored in a tightly sealed container at room temperature for up to four days.
